HAssOs on Mac Mini

Installation
1

Hello everyone.
As you can see from the (many) questions I am a novice user.
I installed Home Assistant OS on a MAC-Mini (early 2009) deleting the previous iOS.
When I start the PC I no longer know how to enter the bios if I want to set the USB boot priority again to install a new OS.

The boot process shows me a screen with Slots A and B.
Always used the first line not knowing what the others do, do you have any clarifications for me?

I can’t find the grub.cfg file which I understand is responsible for the boot. I can’t find it because it isn’t there, in fact the find command doesn’t find anything. What do you recommend?

The installation did not find the drivers for the wifi, not that it is essential but I would like to learn how to solve a problem like this.

Thanks^^

Late to the party, but have done exactly this.

Did you fix it?

Not yet. :frowning: not even with the help of artificial intelligence

I understood that A and B are two HA OS installations, one of which is a backup.
Unfortunately I tried everything, USB with any operating system could run on this door stopper that was once a MAC, installations via ethernet, via cd. I even tried to reinstall snow leopard (think of the point of desperation I reached).
Just today, considering how much it consumes and what it is NOT able to do, I was looking at fanless minipc or similar. With €150 there are interesting things. The recovery of old technology is fine but it must also be economically advantageous in terms of consumption and time to implement.
